Title: Apparatus for monitoring power
Inventor: DUFF JOHN ALEXANDER
IPC: G01R21/00
Filed: 1982-07-23
Abstract: A power level detector device 9 acts to protect receiver circuits 8 from too high a level of incident power. When power at the device 9 is above a certain threshold level the gas contained by the device 9 generates an emission spectrum of electro- magnetic energy. This energy is detected by a photodetector 10 which produces an electrical signal to control the power of a transmitter 1 and hence the power transmitted to the receiver circuits 8. <IMAGE>

Patent GB-2115894-A (GB)
Title: Hydraulic brake control apparatus
Inventor: SANDAU HARTMUT
IPC: B60T13/16
Filed: 1983-01-26
Abstract: The hydraulic control apparatus has a flow regulating valve (16) and a braking device (51, 52, 71, 89). During a braking operation, the pressure medium delivered by the pump is conveyed by the flow regulating valve and a non- return valve (38) to the brake cylinder (89). In that way, pressure is exerted on the piston (52) together with the slide (51) whereupon the latter is so adjusted that a neutral circulation flow from the pump to the reservoir is produced and pressure medium can flow to the braking device. In order to prevent a fixed throttling or seizing of the slide (51) the pressure medium included in an annular space (90) arranged between it and a sealing sleeve (54) must be able to flow away through a throttle disc(91). By using the throttle disc, the pressure difference at the slide (51) is increased whereupon a seizing of the latter is prevented. <IMAGE>

Title: Drive unit consisting of an internal combustion engine and a steplessly adjustable hydrostatic transmission
Inventor: MORANDUZZO GIANPAOLO
IPC: B60W30/18
Filed: 1983-02-24
Abstract: A reversible variable displacement pump (3) is controlled by a servomotor (10) coupled to forward and reverse control valves (16, 18) operated by common controller (19) the control pressure also being applied via shuttle valve (21) and valve (42) to a servomotor (28) controlling fuel supply to an engine driving the pump (31). If the pump delivery pressure exceeds a given value during normal drive, valve (42) vents line (23) and isolates line (24), but during braking this valve isolates line (23) from line (24) and vents the latter to provide hydrostatic braking. Engine speed sensor (53) also causes valve (42) to vent line (23) to relieve any overload. Comparator (58) compares the pressure at (24) with a control pressure from valve (57) and closes throttle (35) when the latter pressure is the higher, this pressure then acting on servomotor (28). A vehicle driven by the engine and hydrostatic transmission also includes a lifting device controlled by element (63) and lever (64) which also closes throttle (35) and actuates servomotor (28) via control valve (65) during operation of the lifting device. <IMAGE>

The pleated bellows (17) is arranged at caliper (15) in a torsionally-secured manner, while it is arranged rotatably at the axial guide bolt (12) close to the fastening point (16), so that the bellows (17) rotates with the caliper (15) as it is swung outwardly. A number of embodiments of bellows (17) are illustrated and described - those of Figures 3, 4, 5 utilize radially inner and outer guard plates for engagement one with the caliper and the other with the bolt. <IMAGE>

Date Mar. 15, 1984.One of several inventions claimed is a method of providing increased traction to the driving wheels of a high speed transportation vehicle. The vehicle is placed within a tubular passageway, equipped with wheels arranged to contact the tube at three or more equidistant contact points, and these wheels are pressed against the inside surface of the tube by means of controlled application of powerful hydraulic pressure. Vertical stability of the vehicle is achieved by a new apparatus comprised of a spoke attached to the vehicle which projects outward to a point adjacent to but not touching the tube, a set of wheels transversely mounted on each side of the spoke, and a pair of L-shaped guide rails between which the wheels roll. An improved wind resisting braking system is claimed which uses extendable baffle plates and air ports from which compressed air is ejected in a direction opposed to the direction of travel.

Title: Synthetic peptides and their preparation
Inventor: GALPIN IAN JAMES
IPC: C07K5/09
Filed: 1983-07-18
Abstract: The enzyme chymotrypsin has many biological functions. It would be useful to inhibit this enzyme for diagnostic and therapeutic purposes. However it is a nuisance to synthesise because it contains the amino acid capreomycidine. The present invention provides peptides which are alternative inhibitors of chymotrypsin and are more readily synthesised than chymostatin. The peptides of the invention are compounds of formula (Org). CO. (BAA). (NAA). X' (al), wherein: Org represents an organic residue, preferably a hydrocarbyl or oxyhydrocarbyl group; BAA represents the residue of a basic acyclic or aromatic amino acid which imparts to the amino acid a pKa of from about 10.5 to about 12.5 and is preferably a lysine, arginine or ornithine residue; NAA represents the residue of a neutral amino acid (being one with no charged side-chain) and is preferably leucine, valine, isoleucine or phenylalanine; X' (al) represents a phenylalanine, tyrosine or tryptophan residue in which the terminal carboxyl group has been replaced by an aldehyde group, and the stereochemical configuration of at least the X' group, and preferably throughout, is of the L-amino acid; derivatives thereof having a functionally equivalent derivative of the aldehyde group, in place of the aldehyde group and the acid addition salts of any of these compounds. The peptides can be synthesised by simple conventional methods. They are useful for diagnosis of chymotrypsin and for therapy, e.g. in treatment of muscular dystrophy.
